Standards are
prepared from appropriate
geological materials.
The ore is ground and then screened through a 270 mesh sieve.
The -270 material (<53 micron) is thoroughly blended.
A minimum of 150 sub-samples are sent
to Canadian and international
commercial laboratories for round-robin analysis. Statistical work is
provided
by Smee & Associates Consulting Ltd.

Please
note: certificates for all standards (those
currently
available as well as those which have been consumed) can be printed
from the "Certificates" page.
